    - Coinstaller question Hi all, I have the following fragment in my inf file: [DestinationDirs] MyCoInstaller.CopyFiles = 11 [MyModelSection] "Printer Name" = MY_DRV,MY_PNP [MY_DRV] CopyFiles = ... DriverFile = ... ConfigFile = ... DataFile = ... HelpFile = ... [MY_DRV.CoInstallers] AddReg = MyCoInstaller.AddReg CopyFiles = MyCoInstaller.CopyFiles [MyCoInstaller.AddReg] HKR,,CoInstallers32,0x10000,"mycoinst.dll,MyEntryPoint" [MyCoInstaller.CopyFiles] mycoinst.dll,,,0x10 [SourceDisksFiles] mycoinst.dll = 1,, mycoinst.dll is in the root of the driver package. After the installation the following appears in the setupapi.dev: ndv:Installing interfaces... dvi:{DIF_INSTALLINTERFACES} 15:40:37.368 !!!dvi: Loading module 'C:\Windows\system32\mycoinst.dll' failed. !!!dvi: Error 126: The specified module could not be found. !!!dvi: Error 126 loading CoInstaller(mycoinst.dll,MyEntryPoint) !!!dvi: Error 126: The specified module could not be found. dvi: No CoInstallers found I expected to have the coinstaller mycoinst.dll in Windows\system32 because of the CopyFiles in the CoInstallers section but it is obvious that it was not there. If I add the MyCoInstaller.CopyFiles in the [MY_DRV] section like this: [MY_DRV] CopyFiles = MyCoInstaller.CopyFiles, ... ... everything is fine. Am I missing something?

    - Filesystem overlay (poor mans unionfs) Hi there. For a legacy application that expects all its customization (.dlls, mostly) in its working directory and because I need to constantly switch projects (which involves "copy the working directory, replace it with another one and restart") I searched for a kind of unionfs[1] for windows, which would allow me to create a logical view on the application directory which includes external directories as neccessary. Sample: C:\MyApp\Bin\ C:\MyApp\Projects\Foo\ I'd like to map all file requests that would fail for the Bin to check another directory again. Being new to this stuff (and doing it out of lazyness, since the process described above sucks) I'd love to hear that this barely involves dispatching IRP_MJ_CREATE? My current idea would be to deploy a minifilter which does the following steps in the PreCreate event: - Check if this request wants a file inside of my Bin directory., else ignore the request - Check if the request is readonly (no create file, no append), else ignore the request - Check if the requested file exists (ZwFileOpen?) and - ignore the request if the file exists - redirect the request to the overlay directory otherwise (setting the filenameinfo and marking the request as dirty) Since I'm bloody new here: Can anyone comment on obvious mistakes? Is this too hard for a beginner's (talking about drivers here) task? Thanks in advance, Ben Tag: Where should I post questions for the Device Simulation Framework Tag: 91547

    - print driver default settings strategy in 2003 server and xp Hi, in a point and print relationship between printQ on 2003 server and xp client, I set up "advanced / printings default" in the print driver option on the server. When the customer install (with point and print method)the printer on the XP, the default setting in the driver match the printQ configuratin of the server. Everything seems ok I use this method for setting up a global print strategy (like force duplex and black and white printing by default).But when the user changes default printing options locally, system keeps this setting as default. I'm looking for a way to allow the user changes setting "on the fly" when printing, but forbid permanent local settings change. In other words, when user opens its application again for printing, default printings option should match the server one. Thanks in advance for your help.

    - WDF supplied functions send reset packet twice through USB Hi All. I am using wdf to make a usb dfu driver. Trying to reset USB device through the call of WdfUsbTargetDeviceResetPortSynchronously or WdfUsbTargetDeviceCyclePortSynchronously I see in the trace that both of them reset device twice. That behavior prevents dfu from proper work. Is it made intentionally? Or am I wrong? How to reset device just single time using wdf? -- Thanks, Stanislav.

    - SDDL string in NdisRegisterDeviceEx() Hi all, further: Running with an SDDL string of "D:P(A;;GA;;;SY)(A;;GA;;;BA) (A;;GRGW;;;BU)(A;;GRGW;;;WD)" and calling NdisRegisterDeviceEx() retruns STATUS_SUCESS, In WinObj I can see the device, and its security is set to: System, Administrators and Everyone: Delete and Query State are checked in the Allow column, everything else is unchecked. Restricted, Query State is checked in the Allow collumn, everything else is unchecked. What ever I set the SDDL to this doesnt change, which is odd. With the result that I cannot open the symbolic link from user land. (My dispatch handler is _not_ getting hit) This is a Miniport ontop of a multifunction USB bus driver (ours). Is there any reason why changing the SDDL doesnt work? Is there any kind of inherited security from the lower bus?

    - bulkusb sample with DTM test Hello, I am new to DTM test. I use Vista DDK's bulkusb sample to transfer MP3 files between PC and Handset. The Handset just has a bulk-in and a bulk-out pipe, and our purpose is just to transfer MP3 files. It works on Vista. Now I use DTM to test it, the .inf shows it belongs to USB class (just like bulkusb.inf). I use usb cable connect handset and pc. And I choose WDK\ConfigureUSBController in MCU Ploicy tab to start DTM test. And then I create a submission(x86 Vista) to run test items(it shows 7 items on DTM Studio) and always failed immediately after I schedule these jobs. All I want to ask are: If the .inf must has a CAT file first and I must add a CatalogFile=XXXX.cat and can not give it a blank CAT file? If I should make a CAT file first and then can do other test items, or they will all fail? Should it must connect through a usb 2.0 HUB? I had test HCT before, it seems simpler than DTM. I am not sure about DTM whether something important that I must to do and I forget to do. Please help me. Thanks.

    - Poor DMA read rate I have a PCI device (32-bit/66MHz) that has a really poor DMA read rate (host to device) that is somewhat decent in one machine (59MB/s) but is really poor in another machine (4MB/s). The performance in the second machine is equivalent to directly reading memory from the host 4-bytes at a time. The DMA write rate (device to host), however, is roughly the same in both machines and close to the theoretical (262MB/s). The device acts as the master for both reads and writes. I have a limited knowledge of the details of the PCI bus. Does this look like an issue with the PCI bridges getting configured differently, resulting in the read transactions being terminated prematurely? I have access to a PCI analyzer and will be setting that up as soon as I have access to the machines again, but I was wondering if this looks like something obvious to someone more knowledgeable about the PCI bus. Also, are there any parameters that can be tweaked to improve the read DMA rate overall? I realize that this is probably highly dependent on the DMA engine on the device itself.

    - Help!! Out of the Pot and into the Driver Fire I need some help. I have been thrown in front of a bus at work. We are having trouble fully testing our network enabled apps for their resilience to the effect of lag and dropped packets and I got tagged as the lucky developer to find a solution. As usual, we can't buy anything; but, in this case I cant find anything that would work anyway. I need to create a small app that will allow me to catch UDP/TCP packets going up and down the stack and hold them for a resizeable amount of time to "fake" lag for our app. I also need to be able to throw out packets based on some known frequency and unknown (psuedo-random). Of course, None of us here are Windows driver developers, but from the research that I've done, it looks like I will need to make a Intermediate NDIS driver and/or Filter driver. I am pretty sure I can't do this project in VS 2005, and I need the WDK....Right? Are there any other things that I will need before I install the WDK? I have been studying the MSDN literature on NDIS intermediate/filter drivers, but I am not real sure where to go next. Thanks a billion for any help.

    - HP lagging in providing printer drivers for Vista my HP1012 laser printer does not work in Vista. I have posted asking for help elsewhere ... I am interested in reading opinions on why HP would be so slow in having printer driver support for printers on Vista. - the 1012 is no longer sold by HP but it is still relatively new. assuming HP is providing Vista support for the printers it sells, will it be difficult for HP to clone one of their working drivers to work with the 1012? - in general are printer drivers harder to write in Vista than XP? - has HP simply become a lame company that has little regard for its legacy customers? -Steve Tag: Where should I post questions for the Device Simulation Framework Tag: 91507

    - USB Selective suspend support by Vista? Our device is a usb 1.1 low speed device with remote wake up capability. and it runs with the Vista in-box hid driver. it also passed USBCV suspend/remote wake up test, Well, after choosing maximum power saving policy in the Vista, we still can not obeserve the driver would send out the "set feature" command to enable the remote wake up function in our device. The deivce keep working on D0, and was not able to go into a power saving state. ""========= Per the ..http://msdn2.microsoft.com/en-us/library/ms793200.aspx In Microsoft Windows XP and later operating systems, the USB core stack supports a modified version of the "selective suspend" feature that is described in revision 2.0 of the Universal Serial Bus Specification. The USB selective suspend feature allows the hub driver to suspend an individual port without affecting the operation of the other ports on the hub. Selective suspension of USB devices is especially useful in portable computers, since it helps conserve battery power. Many devices, such as finger readers and other kinds of biometric scanners, only require power intermittently. Suspending such devices selectively reduces power consumption. More importantly, as long as any USB device remains powered, it will prevent the system from entering deeper sleep states, such as C3. The Windows selective suspend behavior is different for devices operating in Windows XP and Windows Vista. ""========== Once the device keep working on D0, it would prevent the CPU enter C3, it would result in the whole system consume more power.. Does anyone knows 1. The in-box HID driver in Vista support seletive suspend feature? 2. If yes, what's the requirement for arming the command to the device?

    - Multiple MiniportMessageInterruptDPCs on the same CPU In the following scenario, does NDIS call one MiniportMessageInterruptDPC per MSI message or just one DPC call? 1. The driver uses two MSI-X messages. 2. MiniportMessageInterrupt always sets QueueDefaultInterruptDpc to TRUE and returns TRUE. 3. The device sends one MSI message and interrupts a CPU. This causes a DPC. 4. While the last DPC is either running or is scheduled to run, the device sends a different MSI message and happens to interrupt the same CPU. Is this always going to result in another DPC because the interrupt is due to a different MSI message? Thanks... Tag: Where should I post questions for the Device Simulation Framework Tag: 91490

    - 1394 Debugging - So Close - Need Help I've set up my host and target machines for 1394 debugging. I have the virtual 1394 device drivers installed on the host machine and am able to connect to the target machine to begin the debug session. Right after the target's 1394 host controller loads, the debugging connection is lost. When I check the target's hardware properties, the 1394 host controller is whacked. I've read the documentation that warns to disable the target 1394 host controller before debugging with the caution "Be careful not to accidently disable the 1394 net adapter instead". The problem is, when I disable the 1394 host controller on the target, the 1394 net adapter disappears from the listing and thereby not allowing a debug connect at all. Any help would be greatly appreciated. Tag: Where should I post questions for the Device Simulation Framework Tag: 91488

    - IOCTL_SCSI_PASS_THRU commands in limited user mode Hi, Currently I am using IOCTL_SCSI_PASS_THRU commands in admin user mode, when logged in limited user mode I am not able to send IOCTL_SCSI_PASS_THRU commands to an USB device. The reason is Create file will fail due to Generic_read/Generic_write which is not available in limited user modes, and IOCTL_SCSI_PASS_THRU needs these options in DeviceIOControl. As I am working with USB Mass Storage device using usbstor.sys mass storage driver is there a method that would send same commands through USB end points or pipes. Also I found IOCTL_USB_USER_REQUEST which has USBUSER_PASS_THRU option but I could not locate any sample codes, i guess these are not documented. What I am trying to do is to send an vendor specfic command to an USB Mass Storage deivce. Thanks, JK Tag: Where should I post questions for the Device Simulation Framework Tag: 91485

    - machine hanging after reboot when enabling driver verifier When enabling the driver verifier and rebooting the machine (done automatically for some tests by DTM), the machine is hanging during the reboot. I can reproduce the problem also by doing the same thing manually (without DTM). I have Windbg attached and it seems the system is hanging at the very beginning: it seems the driver under test is not loaded yet, the last messages from windbg are "kernel debugger connection established", some stuff about symbol paths and "system uptime: not available" as last message. I'm only able to break into the debugger until after a very long time (more than 10 minutes). The strange thing is that I do not see the problem on all my test machines. I'm currently using 2 machines: the one which has the problem is a single-processor machine, the other one, which is a multi-processor machine, does not have the problem. Another difference between them is that the one with the problem has both XP and Vista installed on it while the other has only Vista installed. Both are 32-bit machines. Has anybody already seen this problem before or does anybody have suggestions to debug this problem? Thanks, Jeroen Tag: Where should I post questions for the Device Simulation Framework Tag: 91476

    - Tcpip.sys bug: FTP Upload. MiniportHalt isnt called untill it has returned all the outstanding sends. So, set up an FTP upload, then do a safe remove. Result, underlying USB bus driver gets the query remove and retuend INVALID_DEVICE_STATE for the Ndis miniport driver writes, but the miniport drivers Halt routine doesnt get called and the device doesnt get unloaded, hanging the PnP manager with device manager showing the device stil present. (You can tell the PnP manager is hung because an inserted USB stick isnt recognised). Via an applet and an IOCTL interface, the Ndis driver can be told to stop, whereupon it cancels all its send packets with a status of NDIS_STATUS_MEDIA_DISCONNECT. After this has hapened the miniport halt function does get called. So, from looking at the DDK: The PnP Manager issues an IRP_MN_QUERY_STOP_DEVICE request. On receiving this IRP, NDIS calls the ProtocolPnPEvent function of all protocol drivers that are bound to the adapter. In this call, NDIS specifies an event code of NetEventQueryRemoveDevice. If a protocol driver fails the NetEventQueryRemoveDevice event by returning a failure code from ProtocolPnPEvent, the PnP Manager might ignore the failure and subsequently succeed the IRP_MN_QUERY_STOP_DEVICE request (but it looks like it doesnt) ... After all protocol drivers are unbound from the NIC, NDIS calls the miniport driver's MiniportHalt function. So, it looks like tcpip.sys is failing the NetEventQueryRemoveDevice because it still has outstanding sends with the Nic driver, but the Nic driver cant complete them till its Halt function is called. Chicken...egg...chicken...egg. This is on XP SP2. I wonder if its 'fixed in Vista', like selective suspend ; ) Tag: Where should I post questions for the Device Simulation Framework Tag: 91474

    - Parallel Dispatching in KMDF drivers I have a PCI hardware with two communication channels. (A and B) Only DeviceIoControl() is used to communicate with this hardware, because there are In- and Outdata for each IRP. In NT4.0 driver I use the standard-queue for Type-A IOCTLs and a user-defined-queue for Type-B IOCTLs NTSTATUS MyDeviceControl(...) { ... switch(pIoStack->Parameters.DeviceIoControl.IoControlCode) { case IOCTL_MY_SIMPLE: // read some bits from hardware and complete IRP ... pIrp->IoStatus.Information=... pIrp->IoStatus.Status=... ntStatus=STATUS_SUCCESS; IoCompleteRequest(...) // no queue used break; case IOCTL_TYPE_A: ntStatus=STATUS_PENDING; IoMarkIrpPending(pIrp); IoStartPacket(...) // the default queue break; case IOCTL_TYPE_B: ntStatus=STATUS_PENDING; IoMarkIrpPending(pIrp); MyAlternateStartPacket(...) // my second queue break; ... } ... } -------------- Now I want to port my driver to KMDF. But I can define only one separate queue for Read, for Write and for IoControl. My Problem is, that I need two queues for IoControl like in my NT4.0 driver, because two User-Mode threads are communicating with my hardware (one thread with channel A, the other with channel B) Question 1: Is it possible in KMDF to return the IRP without using a queue (like IOCTL_MY_SIMPLE) Question 2: Can I direct my IRPs into different queues in KMDF? EvtIoDeviceControl is called for all types IOCTLs. (IOCTL_TYPE_A and for IOCTL_TYPE_B) Thanks Jacques Tag: Where should I post questions for the Device Simulation Framework Tag: 91437

    - Print Monitor Needs to Access Interactive Services I have a print monitor that is installed for a custom Postscript printer driver. This print monitor needs to display a screen asking the user to name a file and select some processing options during the call to LcmStartDocPort. It also invokes a COM object that display several interactive screens to process the file during the call to LcmEndDocPort. The printer driver and monitor installs and runs on OSes Win2K and up. It also installs on Vista, and it will properly interact with the user and process files as designed. However, on Vista the OS intercepts the dialog boxes and displays a dialog titled "Interactive Services Dialog Detection". The message is that "The program [my port monitor] may need information or permission to complete a task." When the user clicks OK, the dialogs are displayed. My questions: 1. How can I properly set permissions (programatically, during the installation) on the port monitor so that it can interact in the user session without the OS intercepting the dialog boxes? 2. Do these permissions need to be applied to the port monitor (a dll) or to the spooler that invokes it? Thanks, Mike Tag: Where should I post questions for the Device Simulation Framework Tag: 91436

Now we need to support Longhorn on all 3 platforms. Since for W2K3 support, I've built 6 drivers (free/checked, x86/x64/ia64). If for Longhorn, I build another 6, that'll be a lot. My questions are: 1. If I use WDK to build a driver for Longhorn in WDK Longhorn build enviroment, could that driver run in W2K3 on same platform ? 2. As a boot-loaded driver, to support Longhorn x64, it needs a embedded signature in driver file. If I do so, could this driver run in W2K3 x64 ?

    - DTM client configuration - is Autologon required? I successfully installed all components of DTM. I then decided to run some tests on sound card drivers currently used by computer on which I installed DTM client (this PC is running Windows XP pro if it matters). All these drivers are signed by Microsoft, so I expected that all test should complete successfully. Was my expectation wrong? Because they all failed. Looking at the test errors I see this several times: ================================= Failed to Wait For Autologon Error Code 0 (The operation completed successfully) Resolution Waiting for autologon in session 0 failed. If you have tasks depending on that session to be present then those tasks will fail until someone logs on to the session. ====================================== Does it mean that PC where DTM client is installed should be configured for Autologon? If yes - what user name should I use? I noticed there is DTMLLUAdminUser created by DTM Client installation, but if this has to be used - what is the password for this account?

    - VISTA Install Windows Drivers (Hardware-First Scenarios) I need to install drivers on VISTA and XP. I will provide a CD containing the drivers. As documented in the SDK and the WHDC site, I have added in my autorun.inf a new directive supported by VISTA, "hardwareid". This is my autorun.inf: [AutoRun] open=setup.exe [DeviceInstall] hardwareid= VID_413C&PID_5128, VID_413C&PID_5128&MI_00, VID_413C&PID_5128&MI_01, VID_413C&PID_5128&MI_02, VID_413C&PID_5128&MI_03, VID_413C&PID_5128&MI_04 DriverPath=\Drivers With VISTA, I am expecting the the "Found New Hardware Wizard" is stopped when I insert the CD containig the drivers, and launch my setup.exe that will preinstall the drivers (using the DIFx DPINST.exe) then give back the hand to the "Found New Hardware Wizard". But this is not the case. What is wrong with my autorun.inf. Olivier Tag: Where should I post questions for the Device Simulation Framework Tag: 91379

    - NDIS: ProtocolUnbindAdapter() gets called at IRQL DISPATCH_LEVEL on Vista I got a problem, where ProtocolUnbindAdapter() of my IM driver gets called at IRQL DISPATCH_LEVEL on Vista, consequently causing a bugcheck 0x7C with 0x14,0x02,0x00,0x00 parameters when calling NdisWaitEvent() to wait for NdisCloseAdapter() to complete asynchronously. I'd like to know, why this can happen (most likely it's my programming error, but still), if the documentation clearly states that ProtocolUnbindAdapter() is called at PASSIVE_LEVEL IRQL. Also, the Debugging Tools documentation must be updated probably, since it doesn't reflect 0x14 parameter in the 0x7C bugcheck documentation. Additionally, when I specifically enable "DbgPrint buffering" parameter in GFlags utility and reboot the system and it crashes with a full memory dump, WinDbg then displays nothing when issuing ! dbgprint command. The nt!kdprint* buffers are empty for some reason. Thanks. Tag: Where should I post questions for the Device Simulation Framework Tag: 91378

    - KMDF inconsistent compiling: order of struct { } members differs I'm writing a KMDF-driver with an IoCtl-Interface. For each IOCTL-code I have defined a C-structure which describes the data passed between driver and the application. These structures interpret the data buffer "inBuf" and "outBuf" on both sides of DeviceIoControl(). So I have several "typedef struct { ... } " declarations. These are located in a separate header .h-file, which is included both in the driver sources and the application sources. So it is garanteed that driver and applications use the same buffer-structures. PROBLEM: I have found at least one struct {}, where the compiler changed the field order, when he compiles the driver. Example: typedef struct { DWORD result; DWORD long_value; char string_value[MAX_STRINGPARAMLEN]; } MyRecord ; When I compile the APPLICATION and declare a variable "mybuffer" MyRecord mybuffer ; then the fields have physically those offsets: mybuffer byte 0..3: member ".result" mybuffer byte 4..7: member ".long_value" mybuffer byte 8..11: member ".string_value" = pointer to character-array = address of mybuffer byte 12 mybuffer byte 12 ... space for string This is as it should be: struct fields are allocate in the order they were defined. BUT when I compile the DRIVER, then there are those offsets: MyRecord mybuffer ; mybuffer byte 0..3: member ".result" mybuffer byte 4..7: member ".string_value" = pointer to character-array = address of mybuffer byte 12 mybuffer byte 8..11: member ".long_value" mybuffer byte 12 ... space for string So the order of members is NOT like defined, the members ".long_value" and ".string_value" were exchanged! The consequences are of course catastrophic, since the driver interprets the integer "long_value" as pointer to the character array "string_value" => end of live as we know it. Thanks for reading so far, I hope the problem is clear now. I searched a lot, but found no #pragma settings which could influence the ordering of struct-members. Only struct-aligning can be modified, but this is not my problem. Some more facts: - I use WinDDK 6000 - driver and application are compiled within the same run of the BUILD-utility - its a checked build for x86 and WinXP platform. - build environment is also an x86 machine with WinXP.

    - USB HID Lower Filter Driver issue under VISTA Hi, I have a problem under MS VISTA with a USB HID filter driver (I developped) attached as low filter on the USB common class generic parent driver (usbccgp.sys) for a USB keyboard device with extra keys. The goal of my filter driver is to change the behaviour or inibit some extra keys of the keyboard. The principle of the filter is the following: it change the HID codes output for the requested keys using a remapping table set in the registry (bytes of code to replace/ bytes of replacing code) and comparing incoming codes and replacing if codes are matching the ones for the keys. Inside the filter driver, the codes are catched thru IRP_MJ_INTERNAL_DEVICE_CONTROL IRP, then IOCTL_INTERNAL_USB_SUBMIT_URB control code, then URB_FUNCTION_BULK_OR_INTERRUPT_TRANSFER function. This filter driver works fine under Windows XP all version. But, now, under vista the filter is installing and running (i can see this thru debug outputs), but it doesn't filter anything: it doesn't catch anymore the function URB_FUNCTION_BULK_OR_INTERRUPT_TRANSFER even if i can see this URB with a sniffer (WDMSniffer). I am not a specialist in driver development and i don't understand what could have changed under Windows Vista comparing to Windows XP ? Does somebody has an idea?

Hi,

is there a good place to post questions regarding the Device Simulation
Framework (USB device sim) ?

Not able to use the SoftUSBEndPointEvents events in managed code...

Thks in advance.

This is not a good place for questions about interfacing c++ and .NET code.
Otherwise, if DSF works for you in unmanaged c++ then yes, a good place.
